Why does my Efco DSH 2500 Brush Cutter engine not reach full speed and emit smoke?

If your Efco Brush Cutter engine isn't reaching full speed or is emitting excessive smoke, first ensure you're using fresh fuel with the correct 2-cycle oil mix. Next, clean the air filter according to the Maintenance-Air Filter Section instructions. If the problem persists, the carburetor may require adjustment, and you should contact a Servicing Dealer.
